Looking for clip on aero bars

[DeLuz]

I would like to try some clip on aero bars on my tandem as I am finding a more aero position is nice riding into headwinds.
I have been just riding at times with my forearms on the tops of bars but it doesn't feel real safe and comfort isn't the best but doesn't seem to bother me.
I borrowed some Profile T1 bars but they are not working out as the elbow pads interfere with being able to use the tops of the bars as I normally do.
So I am looking for something more minimalist that doesn't interfere with my road bars too much. Since I won't be spending long periods of time on the aero bars I am not even sure I need elbow pads.
One bar that looks like a possibility is Deda Parabolica since it looks like the elbow pads would close to the stem.
Thanks for any suggestions.

I have the Deda Parabolica, you can use almost the top of the bar like if there is nothing. 380g for the J-bend and custom pad (10mm foam).
